I have a touchscreen module from a Lenovo AIO PC, can anyone help identify the pin-outs? Answered
Recently I salvaged a 23" touchscreen display from a faulty Lenovo ThinkCentre M90z AIO PC. The PC has a faulty mainboard, but the touchscreen display is in perfect working order. I'm trying to use the touchscreen display for another purpose, but I am having trouble identifying the touch module and its pin-outs.
For your information, the display is a Samsung LTM230HT03
The touch module is made by HannStar, it has the following markings on the back of the board:
HannStar J MV-4
94V-0 1 01 4
On the front of the board is a PXI chip with the following markings:
As well as a smaller chip, which is marked as a MX-70G
I've attached photos of both sides of the module as well as the label on the Samsung display.
There are 4 connectors on the module, CON1 connects to the mainboard, CON2 and CON3 connects to the display, CON4 was not in use.
CON1 has the following wire colours in order from pin 1 to 5: Red, Orange, Yellow, Green, Black.
I will greatly appreciate any help or suggestions that anyone can give.
